For serial installation (fixed lengths), the length of the
exhaust gas sound muffler (Fig. 11-1) and the com-
bustion air intake duct (Fig. 11-2) can be determined
with a pattern. In individual cases the exhaust gas
sound muffler can be shortened. The Truma 35 mm
lock washer tool (part no. 34020-01282) is required
for this. Instructions how to shorten the duct kit are
provided with the 35 mm lock washer tool.

When measuring the combustion air infeed, allow for
a minimum bending radius of 8 cm of the exhaust gas
sound muffler.
Installing the wall cowl
The wall cowls must be ordered separately.

To simplify installation, bend the exhaust duct ac-
cording to the installation position before installing it
on the wall cowl / heater.
NOTICE
Contamination from combustion deposits.
Because of the way a diesel heater works, com-
bustion residue can accumulate on the cowl
outer part.

Install only dark cowl outer parts (anthracite
or black).
Install the wall cowl (arrow pointing up) on an even sur-
face around which wind can flow from all sides.

Drill a hole with a diameter of 83 mm (line the cavi-
ties with wood around the cowl opening). Seal with
the enclosed wall cowl gasket (Fig. 14-6).

Use flexible body sealant on textured surfaces – do
not use silicone.

Before pushing the exhaust double duct through the
hole, slide the clamp (Fig. 14-2) over the duct.

Slide the wall cowl gasket (smooth side facing the
wall cowl, sealing lips facing the wall) onto thecowl
inner part (Fig. 14-9).

Slide the exhaust duct clamp (claws facing the wall
cowl) (Fig. 14-5) over the exhaust duct.

Slide the exhaust duct all the way onto the connec-
tion (Fig. 14-7) and screw in place.

Slide the air supply duct (Fig. 14-3) onto the serrated
connection (Fig. 14-8).

Fasten the combustion air intake duct onto the con-
nection with a hose clamp (Fig. 14-2).

Place the O-ring (Fig. 13-1) on the cowl outer part
(Fig. 13-2).

The O-ring is in the accessory kit of the Combi D.
